“…1 Mainly because of their higher fracture resistance, better stress distribution, [2][3][4][5][6] and lower abrasion of the antagonist enamel, 7,8 highdensity CAD/CAM polymers can be used as an alternative to glass ceramics. Methacrylatebased materials are still among the most commonly used CAD/CAM polymers.…”

STATEMENT OF PROBLEM Polyetheretherketone (PEEK) can be used as a framework material for fixed dental prostheses. However, information about the durable bond to veneering resins is still scarce. PURPOSE The purpose of this study was to investigate the effect of chemical treatments of PEEK on tensile bond strength (TBS) to veneering resins with special emphasis on surface free energy (SFE) and surface roughness (SR). MATERIAL AND METHODS Seven-hundred fifty PEEK specimens were fabricated and divided into the following 3 pretreatment groups (n=250/group): etching with sulfuric acid for 60 seconds, etching with piranha acid for 30 seconds, and an unetched control. After pretreatment, SFE was determined by using contact angle measurements and SR with a profilometer (n=10/group). The topography of pretreated PEEK surfaces was examined with scanning electron microscopy. Remaining specimens (n=240 per group) were conditioned with visio.link or Signum PEEK Bond, or were left untreated as the control group. Half of each group was veneered with Sinfony or VITA VM LC (n=40/group), and TBS was measured after storage in distilled water at 37°C for either 24 hours or 60 days. Data were analyzed by 4-way and 1-way ANOVA followed by the Scheffé post hoc test and chi-square test (=.05). RESULTS PEEK specimens etched with sulfuric acid resulted in higher SFE and SR than specimens without pretreatment or etching with piranha acid. Etching with sulfuric acid or piranha acid led to no general recommendations with respect to TBS. Conditioning with visio.link or Signum PEEK Bond significantly increased the TBS (P<.001). PEEK veneered with Sinfony showed significantly higher TBS values than those veneered with VITA VM LC (P<.001). CONCLUSIONS Sufficient TBS for bonding to veneering resin can only be achieved when additional adhesive materials were applied. ABSTRACTStatement of the problem.

“…Laboratory studies have shown that CAD/CAM designed ultrathin composite occlusal veneers of 0.6 mm thickness yielded a decreased risk of failure as compared to lithium disilicate ultrathin occlusal veneers [26,27]. The use of ultrathin occlusal veneers might be regarded as a conservative approach to treat erosive lesions, with the aim to save as much dental hard tissue as possible.…”

“…16 Rezin kompozit inleyler; kolay yapım teknikleri, düşük maliyetleri ve tamir edilebilmeleri, diş dokusunu azami koruması, estetik olmaları ve diş dokuları ile uyumlu olmaları gibi avantajlarının yanı sıra düşük aşınma ve renklenme gibi dezavantajlara sahiptirler. 14,16,17 İnley restorasyonların başarısında önemli rol oynayan etkenlerden biri kuşkusuz tercih edilen restoratif materyaldir ve günümüzde rezin kompozitler ve seramik esaslı materyaller çoğunlukla tercih edilmektedir. 14,18 Seramikler üstün dişeti cevabı oluştur-maları, estetik özellikleri, inert olmaları, dolayısıyla metal destekli sistemlere oranla ısı ve elektrik iletkenliklerinin daha az olmasına bağlı olarak termal hassasiyetleri azaltmaları 19 ve geleneksel metal destekli restorasyonlara benzer şekilde kenar adaptasyon gösterebilmeleri gibi özellikleri sayesinde son dönemde oldukça yaygın olarak kullanılmaktadır.…”
